Dave Rennie Posted September 14, 2015 Report Share Posted September 14, 2015 Has anyone been successful in making an injector? And if so would they please share some info on it. I've searched te forum but nothing came up. Thanks Dave Quote Link to comment Share on other sites More sharing options...
JRammit Posted September 14, 2015 Report Share Posted September 14, 2015 If you wanna call it an injector, ive made all my soft baits using a copper tube and a tight fitting wodden dowel rod as a plunger The mold must be designed to accept this set up, but to me it was worth the trouble... No nozzle to clean.. No o-rings to replace.. I dont see how it could ever wear out, but if it did I could make a new one for $4 Quote Link to comment Share on other sites More sharing options...
Dave Rennie Posted September 14, 2015 Author Report Share Posted September 14, 2015 Thanks for the reply, I've seen a video of Paul Adams using this method. It's a possible, but I'd rather make a proper injection if it's doable. Quote Link to comment Share on other sites More sharing options...
Roger Linnell Posted September 14, 2015 Report Share Posted September 14, 2015 I made one out of a Cabela's Jerky Shooter, I JB weided an air tool nipple on the nozzle end and built up the piston with silicone to make a goog seal Quote Link to comment Share on other sites More sharing options...
JRammit Posted September 15, 2015 Report Share Posted September 15, 2015 Since ive been having so much fun making videos.. Thought id make one for this thread..... Someone out there may find it usefull Home made injector worm: Keep in mind, this horizontal set up only works for long slender baits (ie worms).. Thicker bodied baits will trap air bubbles in the cavity... This method in a vertical set up would work for any style bait Im currently experimenting with a new method... New video coming soon Quote Link to comment Share on other sites More sharing options...
MonteSS Posted September 15, 2015 Report Share Posted September 15, 2015 I have a real injector for sale for $50. Please dont get hurt trying to make one. Just not worth it. 1 Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted September 15, 2015 Report Share Posted September 15, 2015 JR - good video, very clear and self explanatory. Well done for using a glove on the video too. Dave 1 Quote Link to comment Share on other sites More sharing options...
JRammit Posted September 15, 2015 Report Share Posted September 15, 2015 Please dont get hurt trying to make one. Just not worth it. A verry valid concern!.... Hot plastic under high pressure is a dangerous combination! No matter the tool used, when in doubt remove pressure!... One clog is all it takes Close to (or over) 200 shots with my copper tube in various molds, no accidents (except when i spilled a cup of plastic) Quote Link to comment Share on other sites More sharing options...

Vodkaman Posted September 15, 2015 Report Share Posted September 15, 2015 The main safety issue is blow back past the piston head. I have a mod for the piston that will prevent this; cut a slot about 5mm back from the end. the slot need only be 2mm wide. cut a 2nd slot opposite, forming a 'H'. The idea is that if anything gets past the head, it gets caught in the slot and prevents any further leakage. I used this idea on my piston which was a sloppy fit. The idea worked. A second pair of slots can be cut behind the first, staggered at 90 degrees for additional safety. I can't post images from FireFox and IE is not working at all.

Dave Rennie Posted September 15, 2015 Author Report Share Posted September 15, 2015 Thanks for the replies. Roger, does it work well? Could you post a pic please? JR, thanks for the video, this idea may be worth a shot as the cost is low to try. I'm planning on making multi cavity molds. If you were to make a vertical version, would you pour the plastic in from the top and push down with the dowel, or through the bottom and push up? If it was pour down and push down it should be easy enough to make boxed enclosure around the mold leaving the dowel poking out to avoid safety hazards. I look forward to seeing your new method. Monte, If I can't make a cheep DIY version successfully, I may purchase one thanks. Vodkaman, if you get chance to post a pic I'd be grateful thanks.

Vodkaman Posted September 15, 2015 Report Share Posted September 15, 2015 I live on the outskirts of Bandung which is in the middle of Java, up in the volcanoes. I came here 18 years ago for a short contract, I liked it, so I stayed. The weather is always hot, but cool at night because of the altitude, so I don't need A/C. Living is very cheap and the people are friendly. Dave Quote Link to comment Share on other sites More sharing options...

Heres a vertical mold i made, the top was too thin and it cracked after the first shoot... But the one bait i got was bubble free My current project is a multi cavity using Dave's vacuum method.. And its almost finished! Quote Link to comment Share on other sites More sharing options...
Jig Man Posted September 15, 2015 Report Share Posted September 15, 2015 I have some made from cattle syringes and brass tubes. I use them to make the bait shown between the two. Quote Link to comment Share on other sites More sharing options...

If so, how do you stop the two parts sticking to each other when pouring the second half? Release agent? Epoxy? Modpodge? Quote Link to comment Share on other sites More sharing options...

If so, how do you stop the two parts sticking to each other when pouring the second half? Release agent? Epoxy? Modpodge? This mold is DWP (Durhams water puddy), its stronger than pop and doesnt stick as much... Cooking oil will work on DWP, but vaseline is better... I smear it on with a paper towel until i cant see any swirels The trade off is DWP produces more bubbles, its a little more expensive, and i cant find it in large quantity Quote Link to comment Share on other sites More sharing options...
Dave Rennie Posted September 15, 2015 Author Report Share Posted September 15, 2015 Thanks JR. I've been using RTV for top pour molds so far, but I'd like to find a cheeper solution that will work with two part molds. Quote Link to comment Share on other sites More sharing options...
